Yes. In the highest 1568 lm mode it gets burning hot ridiculously fast, and will drop rapidly in output. I have programmed 980 lm as the highest setting myself. The visible difference is minor and not worth the downsides imo.
Btw, the 980 lumen mode on this light draws significantly less juice...
I have taken som current draw measurements from my h600fc mkiv if anyone is interested.
I measured the 6 highest settings (of 12 total). Battery was a ncr18650b at about 4.1v
12. 1568lm. 5300ma
11. 980lm. 2700ma
10. 562lm. 1270ma
9. 296lm. 550ma
8. 143lm. 230ma
7. 63lm. 110ma
If they stuck with the xp-e R2 to get the right beam profile in this little thing, why did they choose a xp-g led in the neutral version? It doesn't make sense to me. Why can't I have BOTH a little bit of throw AND a neutral tint??
Rechargable batteries are not just marked with "rechargable". They use completely different technologies.
Normal rechargable batteries are NiMH, while normal non rechargable batteries are made with Alkaline technology. Besides the obvious fact that alkaline batteries cannot be charged, they are...
Re: Zebralight SC51 (XP-G R4) & SC50w (XP-E Neutral) 1xAA Reviews: RUNTIMES, BEAMSHOT
The efficiency and features of this light looks extremely nice. I just had to pre-order one. It even has fine regulation on alkaline and L2's. Zebralight seems to be the best at circuit technology by far right...
It all depends on how difficult it is to change modes with the specific flashlight. On my fenixes/quark I just have to tap one or more times quickly from turning it on, it takes less than a second. My LF5XT on the other hand I have programmed to use memory, as its much more time consuming...
Yes, you are probably right about the "recycle mark" and HR6. There is no doubt they are fake though, as they are both longer and thicker than the genuine ones. They also came with a lower charge. All the real ones are between 1.33V and 1.34V, and the fake ones are between 1.15v and 1.22v. I...
It turned out I had a few unopened packs of batteries from dx. The last I ordered had that wierd packaging, but I didn't really thing about it then. Now I read this at dx, and started to compare them to my other unused eneloops. I decided to take some photos of the differences.

Li-ions age a lot just from sitting in a drawer, so I don't buy expensive cells. I buy them all new every year or so anyway. The trustfire 18650's are great. Advertised capacity and no problems yet. The 14500's are a different story.
The purple tint of the E01 is NOTHING compared to the horrible strobing pwm of the L0D. Try going outside with it when it's snowing or raining. It makes my eyes go crazy. I have the LD01 and I like it, but still it seems like I use the E01 more. It's just so simple and reliable, and it's on...
I'm throwing them away in stead, they're cheap anyway.. I was just thinking maybe someone else had experienced the same thing, and I was thinking that it might be the pcb that's the problem, not the battery itself, but I really don't know.. Well, who cares..
I had 8 trustfire 14500 protected batteries in a drawer for about one year. Now that I decided to check on them 5 of them had 3.97V exactly but one had 2V and two was dead (0V). What happened to the dead cells?
Why would some of the cells just rapidly self discharge now when they all came with...
